There it was—the true Light [the genuine, perfect, steadfast Light] which, coming into the world, enlightens everyone.

But if anyone walks in the night, he stumbles, because there is no light in him.”

While you have the Light, believe and trust in the Light [have faith in it, hold on to it, rely on it], so that you may become sons of Light [being filled with Light as followers of God].”

Jesus said these things, and then He left and hid Himself from them.
